Garnet sand, also known as garnet powder or garnet grain, is a versatile natural product that finds use in so many applications. The rock is crushed into sand, so that the small particles can be used in sand blasting given to its ability to act as a good abrasive. It can cut steel and other minerals when mixed with water and used in water jet cutting. This sand is also used in water purification. When the garnet is crushed into very fine pieces, then the sand can also be used in glass polishing and lapping. Finer finishes can be achieved by the fine garnet sand, while the garner sand with larger grain size is ideal for quick work.
